We all begin as a zygote (a fertilized egg with sperm). Zygotes mature from a single cell into a eukaryotic organism by means of what is known as differentiation. What this means is that the cells of a newly formed zygote are normal cells that require the undergoing of differentiation in order to form a complete organism during gestation. Differentiation is simply a process of assigning cells to a specific function and task. Remember in Science, form follows function.Let us assume that a group of cells which have been created through normal cell division (mitosis), are exposed to a specific hormone conducive to kidney function. These new cells will interpret the information from the hormone specific to renal form and function, as a guide to become kidney cells. The very fact that stem cells are able to be influenced by chemical pathways. makes them beyond valuable. What this means, is that cells that are exposed to a specific chemical pathway that influences them to become renal cells. will theoretically do so by synthetic transfer to an individual in renal failure who will simply not make it to the time frame in which a kidney may become available. This is also the case with those who have suffered permanent and debilitating damage (as in the case of Christopher Reeves). Truly, stem cells are hoped for not only the ill but for the human race. in hopes of outliving a general life expectancy conducive to our current time period.Having summarized what stem cells are and what they may be used for, we can begin to approach the controversial topic using first, the principles of structural functionalism. We know structural-functionalism to be a theory that dictates that societies’ very function and stability are maintained by individuals acting in similar manners. In fact, structural-functionalism relies on individuals being not so many individuals as different units of the whole (society as the whole) such that the continuation of the human race depends on such nonautonomy within the individual.
